Mayoral candidate Joe Lhota may be lagging in the polls, but not for lack of financial support from his former employer at MSG.

Sources snickered to us that MSG/Cablevision honcho Jim Dolan sent e-mails to his top staffers, asking them to donate $2,500 each to support their former colleague Lhota’s campaign. The Republican candidate was an executive vice president of Cablevision for five years and, in 2010, he was appointed chief administrative officer at Madison Square Garden.

Though Dolan sent the e-mail to employees back in March, some were still chattering about the political solicitation, particularly as Lhota trails far behind Democratic opponent Bill de Blasio in the polls.

Another source minimized Dolan’s request, telling us: “I assume some people did donate, but it was a small thing.”

However, reports say employees of Cablevision, including those solicited by Dolan, have raised a healthy $94,000 for Lhota’s campaign. A rep for MSG declined to comment.
